Citystar Smart Film: 85% Visible Light Transmittance Grade

Our Citystar smart film with 85% visible light transmittance stands out as one of the most cost-effective options, benchmarked against the classic popular grade from Filmbase. This grade delivers a stable visible light transmittance range of 84% to 86% in its powered-on clear state, paired with a controlled haze value between 4% and 5%. It strikes a wonderful balance between optical performance and competitive pricing, making it extremely well-received by a large number of engineering and commercial projects.

It is important to clarify its positioning first. This specification is not engineered for those ultra-high-end custom projects that demand extreme transparency and ultra-low haze standards. Instead, it is tailored for mainstream commercial scenarios where clients pursue good clear vision, reliable privacy performance when powered off, and a reasonable budget at the same time. For most conventional architectural glass projects, the optical indexes of 84–86% transmittance and 4–5% haze are more than sufficient to meet aesthetic and functional requirements. When energized, the film turns transparent, allowing natural daylight to pass through unobstructed without obvious foggy or milky distortion that would distract viewers. When the power is cut off, it quickly switches to a uniform frosted opaque state, providing instant privacy protection. The transition between the two states is smooth, consistent across the whole film panel, without uneven color, dark edges or delayed switching problems that often appear on cheap inferior smart film.

Thanks to this balanced performance, this Citystar smart film has a wide range of application scenarios. It is a perfect pick for modern office glass partitions and indoor space dividers. Many companies want open and bright office environments for daily communication, while needing fast privacy protection for confidential discussions. Installing this dimming film on glass walls eliminates the trouble of installing curtains, blinds or roller shutters. With one simple switch, staff can freely switch the glass between transparent and private modes.

Conference halls and meeting rooms are another major application field. During regular working hours, the glass stays clear to keep the space open and connected. When meetings involving sensitive information start, users can activate the privacy mode in seconds. Besides privacy, this smart film also supports projection display function. When switched to the frosted off state, the uniform matte surface works as a high-quality projection screen, saving extra space and cost for installing a separate projection curtain. This dual function of partition and projection greatly improves space utilization, which is deeply favored by designers and project contractors.

In museums and exhibition centers, designers often use this smart film to create dynamic display effects. It can be transparent to let visitors appreciate the layout and exhibits behind the glass, or turn opaque instantly to isolate an exhibition area, guide sightlines, or build immersive display scenes. It brings flexible, changeable visual effects that static frosted glass cannot achieve.

High-star hotels, boutique bars and retail shops also widely adopt this grade of smart film. For hotel bathrooms, shower glass and suite space partitions, it provides comfortable privacy while maintaining a high-end minimalist style. In bars and retail storefronts, merchants can switch the glass status according to business hours and activity plans: keep transparent during opening hours to show products and attract passers-by, and turn opaque after closing for safety and decoration needs.

Medical and hospital environments are also suitable for this product. It can be used for consultation rooms, ward isolation partitions and nurse station glass. It helps protect patients’ privacy at any time, while medical staff can keep a clear view when necessary, taking both humanized privacy management and work convenience into consideration.

To sum up, this 85% transmittance Citystar smart film is a high-value mainstream product. It avoids the premium cost of top-tier ultra-low-haze film, yet maintains stable, consistent optical quality and switching performance. It is the preferred cost-effective solution for most general commercial decoration, renovation and new construction projects. If your project does not require the strictest ultra-high transparency and ultra-low haze, this smart film will bring you stable performance, beautiful visual effect and excellent cost advantage.
